It depends a lot on the capacitors. You need a low Equivalent series resistance, so they don't dissipate too much heat with all the switching. People usually use lots of them because a bunch in parallel means the overall ESR is (in my case) 1/24*ESR_EACH.
You can try some large caps, but if they won't work, you'll know pretty quick. They'll get really hot. Try it! See what happens! It might be OK?
